I have a HP Omen 16-c0005AX with a AMD R7-5800H processor. When running cpupower with a normal user, it indicates that the boost state is not active: $ cpupower frequency-info analyzing CPU 1: driver: amd-pstate-epp CPUs which run at the same hardware frequency: 1 CPUs which need to have their frequency coordinated by software: 1 maximum transition latency: Cannot determine or is not supported. hardware limits: 400 MHz - 4.46 GHz available cpufreq governors: performance powersave current policy: frequency should be within 400 MHz and 4.46 GHz. The governor "powersave" may decide which speed to use within this range. current CPU frequency: Unable to call hardware current CPU frequency: 400 MHz (asserted by call to kernel) boost state support: Supported: yes Active: no However it is actually active, but cpupower only correctly detects it when ran as root: $ sudo cpupower frequency-info analyzing CPU 12: driver: amd-pstate-epp CPUs which run at the same hardware frequency: 12 CPUs which need to have their frequency coordinated by software: 12 maximum transition latency: Cannot determine or is not supported. hardware limits: 400 MHz - 4.46 GHz available cpufreq governors: performance powersave current policy: frequency should be within 400 MHz and 4.46 GHz. The governor "powersave" may decide which speed to use within this range. current CPU frequency: Unable to call hardware current CPU frequency: 3.13 GHz (asserted by call to kernel) boost state support: Supported: yes Active: yes Boost States: 0 Total States: 3 Pstate-P0: 3200MHz Pstate-P1: 1300MHz Pstate-P2: 1200MHz cpupower tools used is the one comes with latest stable kernel (6.4).
